为实现穴盘苗的机械自动移栽，设计了一种由取苗器及其驱动机构组成的单动力取苗机构，运用三维软件Pro/E对所设计的取苗机构进行了装配及运动仿真分析，测得取苗器在驱动力作用下位移、速度、加速度等的变化规律。分析结果表明：取苗器在取苗滑道约束下能满足作业要求；但在滑道各阶段的衔接处有硬性冲击产生，所测量即有突变。样机试验表明：取苗器作业流程顺畅，而在取苗滑道连接处确有较大振动，但各项功能均能准确完成，实现了穴盘苗移栽过程中的取苗及投苗两个动作。

In order to achieve plug seedlings transplanting automatically , this paper designed picking seedling machinery which was composed of pick-up device and its driving mechanism with single power .The motive discipline of displace-ment , velocity , acceleration of the pick-up device was measured by using 3 D software through assembling and simulation analysis on the designed picking seedling machinery .It showed in simulation analysis that the pick-up device controlled by slide can meet the operational requirements , but the rigid impact was emerged during the every cross of the slide , that caused the mutation of measurement parameters .Prototype testing experiment showed that the pick-up device worked smoothly , but it produced vibration during the converge of the slide , while various functions can be completed accurately to complete the plug seedling transplanting effectively .
